Yup, lots of grandmas and pas getting really tired of 0.5% savings accounts. Already traumatized by the spectre of 2020, might as well put some money down on the roulette wheel and have some fun.
If the Casinos were actually open and in a different armageddon scenario, I can imagine a lot of the older generation would be flooding the betting tables.
Might re-watch the animated kakegurui again just to get me in the mood.
